颜色动态图形—优化视觉效果的Python编程方法

Python 笔记

一、基础概念介绍

二、实现方法

# 引入必要的库
import pygame
import random
import time

# 定义颜色列表 RGB格式
color_list = [(255,0,0),(255,128,0),(255,255,0),(0,255,0),(0,255,255),(0,0,255),(255,0,255)]

# 定义绘制图形并填充颜色的函数
def draw_rect(screen,color,pos,size):
    rect_info = [pos[0],pos[1],size,size]
    pygame.draw.rect(screen,color,rect_info)

if __name__ == '__main__':
    # 初始化部分
    pygame.init()

    # 创建窗口
    width, height = 600, 600
    screen = pygame.display.set_mode((width, height))

    # 设置窗口标题
    pygame.display.set_caption("Colorful Dynamic Rectangle")

    # 主循环
    while True:
        # 事件处理
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()

        # 随机生成颜色和位置
        color = random.choice(color_list)
        pos = (random.randint(0,width-50),random.randint(0,height-50))

        # 清屏操作
        screen.fill((255,255,255))

        # 绘制图形
        draw_rect(screen,color,pos,50)

        # 刷新屏幕
        pygame.display.flip()

        # 程序暂停，等待0.1s
        time.sleep(0.1)

三、优化视觉效果

color_list = [(255,0,0,50),(255,128,0,50),(255,255,0,50),(0,255,0,50),(0,255,255,50),(0,0,255,50),(255,0,255,50)]

# 添加控制淡入淡出速度的变量
step = 5

# 定义绘制图形并填充颜色的函数
def draw_rect(screen,color,pos,size):
    rect_info = [pos[0],pos[1],size,size]

    # 颜色渐变过程
    for i in range(0,step):
        new_color = (color[0]+(i*(color[0]-color_list[color_idx+1][0])/step),
                     color[1]+(i*(color[1]-color_list[color_idx+1][1])/step),
                     color[2]+(i*(color[2]-color_list[color_idx+1][2])/step),
                     color[3]+(i*(color[3]-color_list[color_idx+1][3])/step))
        pygame.draw.rect(screen,new_color,rect_info)
        pygame.display.flip()
        time.sleep(0.02)

    pygame.draw.rect(screen,color,rect_info)
